I have a Socal 200k 2009 Prius and wanted to know when I should expect my hybrid battery to die?

And let’s also worry when will a 9.0 quake of the San Andreas fault hit L.A.?
No need to worry about it. The HV battery will give you warnings that most people ignore, then it will be $2,000 or less to fix it.
My 2007 with nearly 200k miles has the original battery and I don’t preoccupy myself with it. If ICE runs more or mpg starts falling, I’ll start to focus on it. I occasionally run Dr Prius to check fell voltages and IR. I see no problems. Maybe if you want to do something proactively, get a good quality OBD2 dongle and the free version of Dr Prius.

 

everyone's experience is different. no one can tell you when your car will break down, for whatever reason.
we all have different risk tolerance. i don't take long road trips in older cars, others have driven cars like yours from florida to alaska and back. it just depends on your comfort level.
there's always your cell phone and triple a. but you do read a horror story every now and then

 

My 09 died about 120 days ago 1646 Toyota new battery. Twas toast too. The cars never sat since put on road in 09. My wife’s 10 been commercially driven since new . Other than wiper motor and installing a a 15 battery Hv in car at purchase 650. Nothings ever failed . Err flow is good hi side . Never been touched 267K now . Never a hic up . Now tomorrow cyl no 2 will fail He He..

 

It will last just about as long as your cat.

 

Dr Prius is a useful tool. Just make certain that the OBD2 adapter that you purchase is known to work well with DR Prius on an Android Tablet or Phone.

Dr Prius works good. You just need to buy a Carista Bluetooth adapter on Amazon for $29.99
